With a feed path 214. The ink ribbon 110 that is unwound from the ribbon reel 114 is passed through the first ribbon The guide 210 is guided to the platen roller 120 where it is used for printing, and is then taken up from the platen roller 120 around the open peripheral wall portion 164 (the plurality of second ribbon guides 212) to the take-up core 116. .

The ribbon reel 114 has an ink ribbon 110 and a winding core 112, and has an annular leaf spring 220 that applies a braking load to the winding core 112 (see FIG. 5(b)). The leaf spring 220 is formed in a wave shape in the circumferential direction and is interposed between the top wall portion 156 of the upper casing 152 and the winding core 112 in the axial direction. That is, the rolling core 112 is given a rotational braking load by the elastic force of the leaf spring 220. Thereby, the ink ribbon 110 which is successively wound up by the winding core 116 is given reverse tension to prevent slack.

The rolled core 112 is formed in a cylindrical shape, and a plurality of notches 222 are formed in the circumferential direction at the end portion on the lower casing 150 side (see FIG. 6). Moreover, the rotation stop hook 206 can be engaged with a plurality of notches 222 or detached. Further, the unwinding side bearing portion 202 supporting the lower casing 150 side of the unwinding core 112 is constituted by a circular opening, and the unwinding side bearing portion 202 of the upper casing 152 side is constituted by a cylindrical protruding portion. .

Further, a spline groove 226 is formed in the inner circumferential surface of the winding core 116, and the spline groove 226 is spline-engaged with the winding drive shaft 47. Thereby, the rotational force of the take-up drive shaft 47 is transmitted to the take-up core 116 to wind up the ink ribbon 110.

A platen receiving area 230 is formed on the left side of the base portion in the casing 130 adjacent to the insertion opening 134. The bearing portion 234 (see FIG. 6) formed under the elliptical opening of the lower casing 150 and the bearing portion 232 formed on the elliptical opening of the upper casing 152 are provided at the center of the platen receiving area 230 (refer to Figure 5 (b)). Further, the upper bearing portion 232 and the lower bearing portion 234 are rotatably supported and the platen roller 120 is supported to be slightly laterally movable. That is, the platen roller 120 supported by the elliptical upper bearing portion 232 and the lower bearing portion 234 is configured to be The rest position, which is engaged with the platen drive shaft 45, is laterally moved (small movement) between the clamped position in which the printing tape 102 is sandwiched and contacts the tape guide 194.

However, the tape cassette 100 is conveyed in a state where the winding end portion of the printing tape 102 is slightly protruded outward from the tape outlet 138 (see FIG. 1). At this time, if a press-in force or a pull-in force is erroneously applied to the winding end portion of the printing tape 102, the driven platen roller 120 is moved to the above-described gripping position. Thereby, the unwinding end portion of the printing tape 102 is prevented from being pulled into the crucible case 130 from the take-out port 138.

The platen roller 120 has a cylindrical drum base 240 and a rubber roller 242 attached to the outer circumferential surface of the drum base 240. The rubber roller 242 has a length corresponding to the printing head 21 in the axial direction, and the printing head 21 that has moved to the printing position sandwiches the printing tape 102 and the ink ribbon 110 to come into contact with the rubber roller 242. Further, a spline groove 244 is formed on the inner circumferential surface of the drum base 240, and the spline groove 244 is spline-engaged with the platen drive shaft 45. Thereby, the rotational force of the platen drive shaft 45 is transmitted to the platen roller 120 to print the feed ribbon 102 (and the ink ribbon 110).

[Structure of the side locking portion and the device side locking portion (first embodiment)]

Next, the structure of the side-side locking portion 175 of the tape cassette 100 of the first embodiment will be described in detail together with the structure of the device-side locking portion 57 of the cassette mounting portion 5 with reference to Figs. 7 to 10 . As described above, the attachment base 31 of the mounting portion 5 is provided with a pair of device-side locking portions 57, and correspondingly, the housing 150 is provided with a pair of side-side locking portions 175 under the tape cassette 100. A pair of locking structure portions 174.

As shown in FIGS. 7 , 9 , and 10 , a pair of device-side locking portions 57 are disposed on the mounting base 31 so as to be spaced apart from each other on the right and left sides of the positioning projections 41 . Each of the device-side locking portions 57 is formed in a plate shape parallel to the side plate portion 33, and has a convex body 280 that is erected from the mounting base 31, and a locking hook portion 282 that is provided at a front end portion of the convex body 280. . The locking hook portion 282 has a rectangular cross section and protrudes toward the crotch side locking portion 175, and is provided at its front end portion with an upper edge portion 284, a lower edge portion 286 (edge), and between the upper edge portion 284 and the lower edge portion 286. Flat part 288.

The pair of device side locking portions 57 are arranged such that the locking hook portions 282 face each other. In this case, the hook side locking portion 175 functions as a spring material, and each of the device side locking portions 57 functions as a non-spring material. Therefore, the device-side locking portion 57 is substantially configured as a rigid body and is formed to be strong and short. Further, a mold release hole 290 for forming the device side engagement portion 57 is formed inside each of the device side locking portions 57.

On the other hand, as shown in FIG. 8 and FIG. 9, in the bottom wall portion 160 of the lower casing 150, one of the right and left end portions of the belt accommodating region 190 is formed to be opposed to the pair of device-side locking portions 57. Side latching portion 175. Further, in the bottom wall portion 160, a pair of locking openings 300 are formed adjacent to the respective side-side locking portions 175, and a pair of linear opening portions 302 are formed adjacent to the respective side-side locking portions 175 (linear removal) unit).

In other words, the locking structure portion 174 is constituted by the elastic locking side opening portion 175 and the locking opening 300 and the linear opening portion 302 into which the device side locking portion 57 is inserted. The pair of locking structure portions 174 are disposed in the vicinity of the corner portion where the bottom wall portion 160 and the lower peripheral wall portion 162 intersect. Further, in the left and right ridges of the lower peripheral wall portion 162, one of the portions that are the gripping belts 100 is provided to the finger-receiving projections 304, and the pair of locking structure portions 174 are attached in a plan view (the loading and unloading direction of the self-contained crucible 100) The observation is disposed in the vicinity of the pair of finger rest protrusions 304. Therefore, when the snap-side locking portion 175 is removed from the device-side locking portion 57 by the loading and unloading of the tape cassette 100, the portion of the locking structure portion 174 can be biased without being attached or detached. obstacle.

The locking opening 300 and the linear opening 302 are formed by a slit-shaped opening obtained by removing a part of the bottom wall portion 160 linearly by a band-shaped snap side locking portion 175. In other words, the crotch side locking portion 175 is constituted by a band-shaped portion of the bottom wall portion 160 which is defined by the slit opening 300 in the parallel position, that is, the locking opening 300 and the linear opening portion 302.

The crotch side locking portion 175, the locking opening 300, and the linear opening portion 302 extend parallel to each other and in parallel with the lower peripheral wall portion 162. Further, the side latching portion 175, the locking opening 300, and the line The opening portions 302 have the same length and are formed to be sufficiently longer than the length of the device side locking portion 57.

In this case, the locking opening 300 has a slit width corresponding to the convex body 280 of the device side locking portion 57. Further, the linear opening portion 302 has a slit width that allows deflection of the crotch side locking portion 175. In the relative locking operation of the device side locking portion 57 to the side locking portion 175, the action of inserting the convex body 280 of the device side locking portion 57 into the locking opening 300 and the device side card are simultaneously performed. The locking hook portion 282 of the stopper portion 57 deflects the hook side locking portion 175 toward the linear opening portion 302 side and moves over (locks) the side locking portion 175.

As shown in FIGS. 9 and 10, when the yoke side locking portion 175 is attached to the detachable tape cassette 100 (the detachment direction is the direction of the downward arrow in FIG. 10), the locking hook portion 282 of the device side locking portion 57 is moderate. The ground flexes and flexes. In other words, the crotch side locking portion 175 has a structure in which a portion that is locked by the device-side locking portion 57 (the locking hook portion 282) and a portion that elastically supports the locked portion are integrated. The crotch side locking portion 175 is formed in a beam shape supported by both ends, and has a width that is moderately deflected toward the linear opening portion 302 to exhibit elasticity.

When the tape cassette 100 is attached to the cassette mounting portion 5, the locking hook portion 282 of the device side locking portion 57 comes into contact with the side locking portion 175, and the side locking portion 175 is deflected toward the linear opening portion 302 side. . By the deflection of the crotch side locking portion 175, the device side locking portion 57 is fitted over the crotch side locking portion 175 and relatively fitted into the locking opening 300 to be locked to the crotch side locking portion 175. Moreover, when the tape cassette 100 is detached, the side side locking portion 175 is unlocked (extracted) with respect to the device side locking portion 57 in the reverse order. In addition, when the device side locking portion 57 is formed of a material having a Young's modulus lower than that of a metal such as plastic, the device-side locking portion 57 is formed into a shape that is not easily elastically deformed by increasing the thickness thereof, and functions substantially as a rigid body. It can be regarded as a rigid body that is not easily damaged.

When the band 100 is attached, the locking hook portion 282 comes into contact with the crotch side locking portion 175 in the order of the upper edge portion 284, the flat portion 288, and the lower edge portion 286 (see FIG. 10). Moreover, when the band 100 is detached, the locking hook portion 282 is in accordance with the lower edge portion 286, the flat portion 288, and the upper side. The order of the edge portions 284 is in contact with the crotch side locking portion 175 (refer to FIG. 10). Here, the upper edge portion 284 and the lower edge portion 286 may not be sharp edge edges, and may have a small chamfer or an arc having a very small radius of curvature. Further, in order to smoothly bend the side locking portion 175 with respect to the locking hook portion 282 at the time of attachment and detachment, the side locking portion 175 is provided with a guiding slope 312 (first guiding surface). The pressed inclined surface 314 (second guiding surface) and the guiding surface 310 that connects the guiding inclined surface 312 and the connecting surface 316 of the pressed inclined surface 314.

The guide slope 312 generates a force for deflecting the side locking portion 175 toward the linear opening portion 302 with respect to the force of the mounting direction of the tape cassette 100 in the mounting direction. Therefore, the guide slope 312 is formed in such a manner as to form an acute angle with respect to the mounting direction. That is, the angle formed by the mounting direction and the guide slope 312 is 90 or less. Thereby, the crotch side locking portion 175 is easily bent, and the locking hook portion 282 can be smoothly passed.

Similarly, the pressed bevel 314 is a force for deflecting the crotch side locking portion 175 toward the linear opening portion 302 side with respect to the force in the mounting direction when the band 100 is detached. Therefore, the pressed slope 314 is formed to form an acute angle with respect to the detachment direction. That is, the angle between the detachment direction and the pressed slope 314 is 90° or less. Thereby, the crotch side locking portion 175 is easily bent, and the locking hook portion 282 can be smoothly passed.

Further, the pressed inclined surface 314 is a portion where the lower edge portion 286 of the locking hook portion 282 is in contact with the locking hook portion 282. In other words, in a state where the click side locking portion 175 is locked to the device side locking portion 57, at a specific position of the pressed inclined surface 314 (in the cross-sectional view of FIG. 10, the lower edge portion 286 is in contact with the pressed inclined surface 314). The point contact position) is in line contact in a direction in which the lower edge portion 286 extends. That is, it is not a large-area surface contact, but a point contact with a small contact area is a linear continuous line contact. In other words, the crotch side locking portion 175 is pressed against the upper edge portion 284 and the lower edge portion 286 of the device side locking portion 57 by the flat portion 288 which is not close to the wall surface of the edge. The 314 is in contact with the lower edge portion 286 to be locked. Thereby, the elastic force of the crotch side locking portion 175 acts on the locking hook portion 282, and the band force 100 is pressed against the attachment base 31 by the reaction force (component force).

Further, since the contact area at a specific position is small as described above, it is possible to suppress variations in the elastic force or the reaction force (component force) of the crotch side locking portion 175. Thereby, it is possible to set an accurate elastic force or the like according to the design value. Further, the lower edge portion 286 does not have to extend linearly in the direction perpendicular to the paper surface of FIG. 10 (the direction from the front side toward the deep side of the paper surface), and the lower edge 286 may be set to be perpendicular to the paper surface of FIG. The curved shape causes the lower edge 286 to be in three-dimensional contact with the pressed bevel 314.

When the tape cassette 100 is attached to the cassette mounting portion 5, the pressed bevel surface 314 of the crotch side locking portion 175 is formed not to follow the flat portion 288 of the engaging hook portion 282 as shown in FIG. 10(a). And the shape of any of the hook lower portions 289. Thereby, when the tape cassette 100 is detached from the mounting portion 5 and attached, the lower edge portion 286 can slide on the pressed slope 314. Therefore, when the strap 100 is detached from the cymbal mounting portion 5, the hook lower portion 289 does not "engage" with the pressed inclined surface 314, and the detachment is prevented. Moreover, when the tape cassette 100 is attached to the cassette mounting portion 5, the belt edge 100 can be positioned on the cassette mounting portion 5 by pressing the pressed slope surface 314 by the lower edge portion 286.

In other words, in FIG. 10, the pressed inclined surface 314 and the lower edge portion 286 are in a state in which they are in contact with each other at a position other than the contact point, and are in contact with the point contact, whereby the tape cassette 100 is attached to the cassette mounting portion. In the state of 5, the locking portion 175 is in contact with the lower edge 286, and the focus of the spring is clear. Therefore, when the belt cymbal 100 is detached in accordance with the designed elastic force, the force of pulling out the belt 匣100 is applied in the upward direction of the arrow of FIG. 10, whereby the 匣 side locking portion 175 is turned toward FIG. 10 ( b) The horizontal direction arrow shown moves in the right direction, and the lower edge 286 slides on the pressed slope 314 to easily complete the detachment.

The connecting surface 316 is a portion where the deflection of the side-side locking portion 175 which is in contact therewith when the belt 匣100 is attached is reached. Therefore, the portion in contact with the locking hook portion 282 at the time of mounting is transferred from the connecting surface 316 to the pressed inclined surface 314, thereby obtaining a feeling of sensation at the time of mounting. Further, at the time of detachment, the portion in contact with the locking hook portion 282 is transferred from the joint surface 316 to the guide slope 312, whereby the sensation at the time of detachment is obtained. As described above, the moment when the deflection of the side locking portion 175 reaches a peak is only one of the moments in the middle of the loading and unloading operation of the belt 100, so even if the belt is twisted, It is also possible to prevent the elastic force of the crotch side locking portion 175 from being lowered due to creep deformation or the like by continuously attaching to the cymbal mounting portion 5 for a long time.

Furthermore, the guiding slope 312, the pressed slope 314, and the connecting surface 316 may not necessarily be flat surfaces. That is, the guiding slope 312 may be a curved surface in which the respective portions form an acute angle with respect to the mounting direction. Similarly, the pressed slope 314 may be a curved surface in which the respective portions form an acute angle with respect to the detachment direction. Further, the connecting surface 316 may also be a curved surface.

Further, the loading and unloading direction of the belt 匣100A is the direction of the arrow in the upper and lower directions in FIG.

On the other hand, the device-side locking portion 57 has the same configuration as that of the first embodiment, and is erected on the attachment base 31 so as to correspond to the locking opening 300. In this case, the locking hook portion 282 of the device side locking portion 57 is also formed in a rectangular cross section. Further, similarly to the first embodiment, the side surface locking portion 175 is formed with a guide surface 310 having a guiding slope 312, a pressed slope 314, and a joint surface 316.

Further, in this case, the angle formed by the mounting direction and the guide slope 312, and the angle between the detachment direction and the pressed slope 314 are all 90 degrees or less. Thereby, the loading and unloading of the belt cassette 100A can be smoothly performed, and a moderate feeling can be obtained. Further, the tape cassette 100A can be pressed to the mounting base 31. Further, in the second embodiment, as compared with the first embodiment, the distance (the distance between the fixed positions) can be increased between each of the side-side locking portions 175. A more stable installation with 匣100A.

As described above, according to the present embodiment, the side locking portion 175 has the guiding slope 312, the pressed slope 314, and the connecting surface with respect to the device side locking portion 57 having the locking hook portion 282 having a rectangular cross section. Since the 316 is used as the guide surface 310, the loading and unloading of the belts 100, 100A can be smoothly performed, and a moderate feeling can be obtained. Moreover, the tape cassettes 100 and 100A can be appropriately locked in a state of being pressed to the cassette mounting portion 5.

Further, when the tape cassettes 100 and 100A are attached to the cassette mounting portion 5, the portion where the specific position of the side side locking portion 175 is smaller is locked to the smaller portion of the specific position of the device side locking portion 57. (The lower edge portion 286 is in contact with the point of the pressing surface 314 in a cross-sectional view as shown in Fig. 11), and therefore, the tape cassettes 100, 100A can be accurately positioned and held by the frame mounting portion 5 in accordance with the design force. Therefore, even if the tapes 100, 100A are subjected to a force from the printing head 21 or the like, the positional deviation does not occur and does not rise.

Further, since the snap side locking portion 175 (the locking structure portion 174) functioning as a spring is provided on the side of the tape cassette 100, 100A, it is not necessary to make the device side locking portion 57 elastic, and the device side can be shortened.
